I would like to dynamically switch the video source in a streaming video application. However, the different video sources have unique image dimensions. I can generate individual SDP files for each video source, but I would like to combine them into a single SDP file so that the viewing client could automatically resize the display windo...
I am looking for more information about the minimum requirements needed for a visitor to successfully stream a 1 Mbps 640x360 H.264-encoded video. I know that the user needs the latest Flash 9 version. I am looking for the minimum requirements for their computers. We want to switch to this codec for our videos, but do not want to ruin o...
How can I encode an h264 video to be MDC (multiple description coding) ...
I am trying to build a video player application using Adobe Flex and libh264streaming. In small cased my little player works just fine. However if the video is bigger about 200-300MB I am seeing bunch of issues: a) the browser get crashy b) it never stops buffering , keeps downloading until it gets entire video (300M) c) CPU usage goe...
I have a engine to check the H264 video is compliance with AVCHD or BDMV spec, the SPEC mentions the MAX system data rate is up to 24 Mbit/s, I want to know how to calculate the system data rate? Does it mean the average of whole file? Or does it mean the average of 1 second? ...
The main players seem to be x264, and xvid, and both are GPL. This means we can't integrate decoding capabilities into a playback application without licensing the whole thing as GPL, so we can't use either. The preferred target platform is Linux. Any non-viral open license is fine, we're more than happy to provide the source of any ch...
I'm looking for an order of magnitude estimate for expected on-disk file size for 1 hour of H.264 encoded HD video transcoded from HDV (HD on a MiniDV tape). I want to archive approximately 100 hours of such content and want to figure out whether I'm looking at a big hard drive, a multi-drive unit like a Drobo, or an enterprise-level sto...
I'm trying to render frames coming from an mkv h264 file in silverlight 3 by using the MediaStreamSource. Parsing the mkv file is fine, but I'm struggling with the expected values for CodecPrivateData in SL, which has to be a string, while the PrivateData info from mkv is a binary element. Also, I'm not sure about in which form the frame...
Hi, I'm looking for a web player with the following features : - Play h264 in HD - Feeware - Good buffering control Actually, I'm using JwPlayer but it doesn't support buffering ! ...
Hi, i am trying to make ffmpeg or x264 provider that will encode videos.. Well i have been looking at some tools and such and. i don't know.. I would need to make my own api. I have done the same 4 ffmpeg for flv1 but h264 seems much different.. can anyone give me some basics where and how to start? ...
I've got a video camera that I'm using to capture video; the camera records in H.264 at 720p resolution. I'd like to transcode this stuff to a simpler, smaller format; something that will work properly on digital photo frames that support video, for example. As well, I'd like to transcode to DVD format where possible, so I can burn DVD...
Hi, i have made my video encoder. well very simple one and my process stops working after it gets to certain percent. Is there anything i could do to make it work? Is there some memory limitation? Could i run it somehow different? ...
Considering the amount of pressure each of the algorithms for decoding put on the processor, how is streaming video (real time) from web cam chat servers decoded in the mobile devices like cell phones? Is it displayed using a flv player (more or less like uploading a video on to youtube and simultaneously viewing it elsewhere. With this...
I am evaluating WPF and Silverlight for a Project. I find WPF to be most suited for our purpose since we require performance, graphics support, Office compatibility and the ability to support ActiveX controls. It is also a Desktop application. However there is one area where i find Silverlight to be superior - Media support. I would like...
I have a fairly high-end webcam (snc-rz25n) that I need to rebroadcast using the Flash Media Server. I can get the picture as MPEG-4 (not h.264). So I need to transcode to h.264 and publish at multiple bitrates to FMS. The only solution I have been able to come up with thus far is to transcode the stream using ffmpeg and then also use f...
I've got a Sony network camera (SNC-RZ25N) that I am trying desperately to get data from in some meaningful format. The documentation says it sends MPEG-4 raw data, but is not more specific than than. I can capture a segment of the stream using curl ( http://techhead.biz/media/tsv.m4v ) and it will play using VLC and ffplay (though it pl...
I'm working on a streaming video player that can play either FLV or H264. I have it working on the PC and my attempts to get the Wii to play H264 have come up short. With the recent browser update the Wii has Flash Lite 3.1 (upgraded from Flash 7) which has support for H264 (Adobe Flash Lite version comparison.) I've tried different b...
I am looking for h264 decoder C/C++ source code with RTP packetization support. My embedded device is sending 640x480 encoded h264 RTP packet. I would like to make a Windows XP/Vista based video streaming display. Where can I find the source code to this? ...
Hello All, I'm wondering if someone can help me with references or code snippet of H.264 files splitting. ...
Hi, The function below contains nested for loops. There are 3 of them. I have given the whole function below for easy understanding. I want to parallelize the code in the innermost for loop as it takes maximum CPU time. Then i can think about outer 2 for loops. I can see dependencies and internal inline functions in the innermost for loo...
